A zebra went to heaven. When he saw St. Peter he asked him You know, I have always wondered, am I a white horse with black stripes or a black horse with white stripes? St. Peter said he would have to ask God that question since hes the one that made him.

So the zebra asked God, God, am I a white horse with black stripes or a black horse with white stripes?
God answered, You are what you are. The zebra left and came upon St. Peter and told him,
Well I asked God if I was a white horse with black stripes or a black horse with white stripes…
What was the answer, St. Peter asked. Well I still dont know. All He said was: You are what you are. Well that answers it, Said St. Peter. Youre a white horse with black stripes. How do you know that? asked the zebra. Well if you were a black horse with white stripes He would have said: You is what you is.
